Plano-convex lenses inoburitsa kushomeka kwedenderedzwa kana yakatarisa kune infinity (apo chinhu chemufananidzo chiri kure uye conjugate ratio yakakwira). Naizvozvo ndiwo ekuenda-ku-lens mumakamera uye teresikopu. Kunyanya kushanda kunowanikwa kana plano yakatarisana nendege inodiwa, nemamwe mazwi, nzvimbo yakakomberedzwa yakatarisana nedanda rechiitiko. Plano convex lenzi isarudzo yakanaka yekubatanidza mwenje kana yekutarisa maapplication uchishandisa monochromatic mwenje, mumaindasitiri akadai semaindasitiri, emishonga, marobhoti, kana kudzivirira. Iwo isarudzo yehupfumi yekuda maapplication nekuti ari nyore kugadzira. Sekutonga kwechigunwe, plano-convex lenses inoita zvakanaka kana chinhu nemufananidzo zviri paabsolute conjugate ratios > 5: 1 kana <1: 5, saka spherical aberration, coma uye kukanganisa zvinoderedzwa. Kana iyo mhedziso inodiwa kukudza iri pakati pezviviri izvi zvakakosha, Bi-convex lenzi anowanzo kuve akakodzera.
ZnSe lenzi dzinowanzo shandiswa muI IR imaging, biomedical, uye mauto maapplication, akanyatsokodzera kushandiswa nepamusoro-simba CO2 lasers nekuda kwekuderera kunyura coefficient. Mukuwedzera, vanogona kupa hutachiwana hwakakwana munharaunda inooneka kuti ibvumire kushandiswa kwedanda rekugadzirisa tsvuku. Paralight Optics inopa Zinc Selenide (ZnSe) Plano-Convex (PCV) Lenses inowanika nebroadband AR coating yakagadziridzwa 2 µm - 13 μm kana 4.5 - 7.5 μm kana 8 - 12 μm spectral range yakaiswa panzvimbo dzose dziri mbiri. Kupfeka uku kunoderedza zvakanyanya avhareji yekuratidzira kweiyo substrate isingasviki 3.5%, ichipa avhareji kutapurirana inodarika 92% kana 97% pairi rese AR coating renji. Tarisai maGrafu anotevera kune mareferensi ako.
